History of the use of chemical weapons for military purposes and the possibility of their current use

Throughout the history of mankind there have been many wars of both local character and large-scale wars. At the heart of military actions necessarily lies the use of weapons, one type of which is chemical. Chemical weapons, the basis of which are diverse in their effect on the body and chemical composition of poisonous substances, began to be used for military purposes during World War I, namely, the first use occurred on April 22, 1915 in Belgium near the city of Ypres. Germany used gas cylinders filled with chlorine in this attack. The man who created this weapon was German chemist Fritz Haber, who became known as the "father of chemical weapons". Since that time, scientists from different countries began to actively study the effect of poisonous substances on the human body, synthesize their new types, as well as search for reliable means of protection against its effects. Throughout history, attempts have been made to ban the use of chemical weapons. In particular, after the end of the First World War, the Geneva Protocol was adopted in 1925, prohibiting the use of asphyxiating, poisonous or other similar gases in war. However, this agreement failed to limit the use of poisonous substances, which led to their further use, mainly in localized wars. Much work on the prohibition and destruction of chemical weapons belongs to the Organization for the Prohibition of Chemical Weapons, established in 1997 after the adoption of the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on Their Destruction in 1993. The purpose of this paper is to summarize the history of chemical weapons for military purposes, as well as to study the activities for their prohibition. Literary data of recent years on the history of creation, use of chemical weapons and international legal agreements on their prohibition and destruction, the main types of toxic substances, means of protection against their effects are analyzed. Conclusions are made about the possibilities of chemical weapons use at present.
